Brain Volume, Intracranial Volume, and Dementia
Investigative Radiology, 2001Using a large magnetic resonance (MR) imaging data set (n = 532), we investigated the utility of total intracranial volume (TICV) as a correction factor for head size variability when assessing total brain volume (TBV) and the subcortical volumes of the temporal horn of the lateral ventricular system and the hippocampus.A uniform tissue segmentation ...

Effect of inspired volume on closing volume
Journal of Applied Physiology, 1976Closing volume (CV) was ?EASURED WITH THE RESIDENT GAS TECHNIQUE IN 12 HEALTHY SEATED SUBJECTS AGE 22–70 YR, AND IN 8 SUBJECTS WITH THE BOLUS TECHNIQUE. Various volumes were inspired (Vi range: 20–100% vital capacity) fromresidual volume and CV was assessed on the subsequent recording of expired volume versus gas concentration.

Cognitive Psychology, 1999
The visual system completes image fragments into larger regions when those fragments are taken to be the visible portions of an occluded object. Kellman and Shipley (1991) argued that this "amodal" completion is based on the way that the contours of image fragments "relate." Contours relate when their imaginary extensions intersect at an obtuse or ...

Progressive Direct Volume-to-Volume Transformation
IEEE Transactions on Visualization and Computer Graphics, 2017We present a novel technique to generate transformations between arbitrary volumes, providing both expressive distances and smooth interpolates. In contrast to conventional morphing or warping approaches, our technique requires no user guidance, intermediate representations (like extracted features), or blending, and imposes no restrictions regarding ...

Volume seeds: A volume exploration technique
The Journal of Visualization and Computer Animation, 1991AbstractRay‐traced volume rendering has been shown to be an effective method for visualizing 3D scalar data. However, with currently available workstation technology, interactive volume exploration using conventional volume rendering is still too slow to be attractive.

Volume-Limited and Volume-Targeted Ventilation
Clinics in Perinatology, 2012This article shows that volume-targeted ventilation is physiologically more logical than pressure-limited ventilation, and is associated with a reduced risk of pneumothorax, hypocarbia, duration of ventilation, death or bronchopulmonary dysplasia, and severe intraventricular hemorrhage.

Lung volume, closing volume, and gas exchange
Journal of Applied Physiology, 1982The effect of a voluntary reduction in lung volume on arterial O2 saturation (SaO2) was studied in 10 normal subjects aged 19–63 yr. SaO2 was measured by ear oximetry first during tidal breathing at functional residual capacity, and then during tidal breathing at 380 ml above residual volume.

Definition of volume transformations for volume interaction
1997Volume transformations of medical images play an important role for many applications such as registration of different modalities, mapping atlases onto clinical data, or simulation of surgical procedures. While registration and atlas mapping can for the major number of applications be performed without tight time constraints, it is essential for ...
